Y My invention relates to `harvesters adapted to be propelled over a field of grainfor cutting land threshing the grain therein. Such harvestersmust beadaptable to all diterent v contours and conditions of terrainyincluding not only level' elds but also rolling country and hills. In Yharvesters non7 constructed it is essential in the harvesting operation that Vthe separating mechanism be kept approxii'n matelylevel despitefthe `character of4 the countryover which .the vehicle is propelled.

To meet this-need harvesters have been constructed :tor operation on hillsides and in rolling `country and'these are usually termed side-hill harvesters; They are' provided with manufacturing scheme` `and they'` are Vdealt l with: in V"commerce as two distinct. types of mechanism. f

It is an object of my invention to. provide an attachment for a standard level land harvester which will permit it to be used as a side-hill machine. i j l Anotherobject of my invention is to simplify the mechanism for adapting a harvester to side-hill work. Y f

Another object of my invention is to Vprorvide a power operated means for adjusting the side-hill harvester to different degrees of ground inclination. i i Y Y 40 A further object of my invention is to provide an improved supporting means for the p side-hilll adjusting mechanism. i 'The foregoing and' other objects' are att-ained inthe embodiment of th-e invention 45. shown in the drawings, in which attachment applied toia'harvester.

It Will be appreciated that I have provided'v i a harvester attachment Which can, be appli-ed to a standard harvester With substantially no change thereof and Which renders the standard harvester variable for use in hilly and undulatory country. Furthermore, the power required to effect the adjustment of the harvester to its peculiarconditions is.

derived from the engine and ispcompletely under control of the harvester operator.`
